ABSTRACT:
A reverberation apparatus includes a signal input terminal to be supplied with an input signal, an operational amplifier having an inverted input terminal, a non-inverted input terminal, and an output terminal. The inverted input terminal is connected to the signal input terminal through an input impedance circuit. The non-inverted input terminal is connected to a reference point, and the output terminal is connected to the reference point through an inductance circuit as a load and a first impedance circuit. A second impedance circuit is connected between the inverted input terminal of the operational amplifier and the connection point between the inductance circuit and the first impedance circuit. In this circuit, the inductance circuit functions as a drive circuit of the reverberation apparatus.
